' 5 Claims. (Cl. Ils-283) Power wringers involve an element oi'danger in that the operator may get caught in the rolls, or the clothes may get entangled in the rolls so as to injure them. Under either of these conditions it is necessary to have means by which the pressure on the rolls may be immediately relieved. In any case the operator is usually agi# tated. It is desirable, therefore, that the means by which the relief of pressure is accomplished may be operated with the most natural and instinctive action of the operator. To thisend the present invention provides an operating means which will relieve the pressure when actuated forward or back, or sidewse so that with practically any action, or response of the operator the release is accomplished. At the same time the device should be locked in place as against accidental release and the presentinvention while very` sensitive to release affords this release. Features and details of the invention will appear from the specification and claims.

A preferred embodiment of the invention is illustrated in the accompanying drawing as foilows:-

'I'he frame has the base I with the side stiles 2.

Rolls 8 and l are mounted inthe frame, the rolls having the usual shafts i and voperating ln bearings 'I and 8. A top bar 9 is of channel form with closed ends and extends over slightly -telescoping the upper ends of the stiles. A spring III forms the pressure device of the wringer. An adjusting screw I I lextends from the cross bar to the spring and the ends of the spring rest on the upper bearings 8 so that the pressure of the spring is communicated to the rolls.

The upper endof one of the stiles has a lip I2 at its-outer wall forming a shoulder and a corresponding lip I3 is formed in the end of the cross bar forming a shoulder I 4 below the lip. When the cross bar is in place,- the shoulder Il engages the lip i2 and thus locks the cross bar against disengagement except as the opposite end of the cross bar is swung upwardly so as to permit of a, slight endwise movement of the parts.

Latch plates I5 are arranged at both sides of the stile at the opposite side of the wringer and 55l these plates are connected by a cross plate I8.

o! the wringer,v

The latch plates are provided with pivot openings I1 into whichlugs I8 struck up'in the side walls of the stiles extend. A trip lever 'I8 extendsover vthe top and one end of the cross bar. It has the side flanges 20 which extend down along the sides of the cross bar and has the inturned lips 2| along its lower edge. A pivot exhooks to the pivots of the latch plates I5. Inl

order to release the hook, the lip 2| is tilted and .as soon as it is tilted, thehook slides of! the lip,

thus disengaging the top bar. In order to prevent an accidental disengagement a spring 26 is provided for the lever I8 and the plates I5 are provided with shoulders 26 which engage the outer ends of the lips 2|. Thus the hooks 2l are prevented from moving ofi the lips 2l until the lever I8 is depressed, thus lifting the outer edge ofthe lip 2I out of engagement with the shoulder.

The top bar has an extension 21 forming a platform. A rocker base 28 rests on this platform and a lever 28 extends upwardly from the rocker lever having a ball handle at its upper end. The lower end o1' the lever has aV projection 3l which extends into a perforation l82 on the platform so as to locate the lever.

'It will be noted that by engaging the handle 80 the lever may be rocked in any direction and as it is rocked the outer edge of the rocking base 28 at the side toward which the lever is moved forms a fulcrum and the opposite edge of this base operating under the lever I8 raises the lever I8 and consequently releases the latch.

1. In a wringer, the combination of a frame; rolls mounted in the frame; pressure means for the rolls exerting pressure from the frame on the rolls; a safety release device 4for the means adapted to release the pressure means; and actuating means actuating the device, said actuating means including a handle operable to actuate the means by a horizontal force applied thereto in any dlrection.

2. In a wringer, the combination of a frame; rolls mounted in the frame; pressure means for the rolls exerting pressure from the'frame on the rolls; a safety release device for the means adapted to release the pressure means; and actuating means actuating the device comprising a lever with a rocking base, said base responding to on the latch to release the bar, said actuating means releasing the latch in response to substantially horizontal movement in any direction.

4. In a wringer, the combination of a frame; rolls mounted in the frame; a cross bar on the frame; pressure means exerting pressure on the rolls from the cross bar; a platform on the cross'- bar; a' latch locking the cross bar on the vframe; and a safety release device operating on the latch to release the bar, said safety release devioecom- :madam prising a lever a rocking base, said being mounted on said platform rocking relatively to said platform and relatively to said latch and releasing the latch as it is rocked.

5. In a wringer, the combination of a frame; rolls mounted in the frame; a top bar mounted on the frame; pressure means operating from the top bar on the rolls: a latch securing the top bar on the frame; a releasing lever on the cross bar locking the latch with the cross bar; a platform on the top bar; anda rocking lever having a rocking basemounted on the platform rocking relatively to said platform and relatively to said latch, said rocking base actuating the release lever as it is rocked to release the latch.
